My son (aged 15) and I both observed it. It was a clear bright sky. Purely by chance we were staring straight up in the sky commenting on how cold and clear it was, and how visible the stars were. It had a "v" shape ie with a tail. It moved faster than I have ever seen anything move in the sky ! From where we were standing it passed almost overhead, left to right, in a line slightly to the SW of us. I have no idea how much distance relative to the ground these objects cover but from having looked at a map, from where we were standing it looked as if it came from roughly the direction of High Wycombe and was heading towards Cirencester.
